Who is Venezuela opposition leader Juan Guaido?

Juan Guaido, the man challenging Nicolas Maduro, once expressed horror over the 1992 coup in Venezuela, yet ironically, he just launched his own military uprising.

Until recently, Venezuela’s opposition leader, Juan Guaido, was unknown internationally.

In 2010, he toured his hometown, hoping to become the youngest congressman that year.

Now, he is recognised by more than 50 countries, led by the United States, as Venezuela’s interim president and is the biggest threat to Venezuela’s ruling party.
